Related: "In general, Acrobat and Reader will show a negative image when the image data indicates that it needs to be inverted. When you have images that are compressed with the CCITTG4 algorithm, there is a flag in the image data that indicates if a logical "1" indicates black or white. The software that created this document must have used the wrong value for this flag. I've seen similar effects also with certain CMYK JPEG images (but it's been years since I encountered the last one of those) where the PDF generator created corrupt data."
